IMPOVEMENT lN REFLECTlNG CHANDELIERS.

Specification forming part of Letters Patent No. 124,582, dated March1'2, 1872.

To all whom it may concer-n:

Be it. known that I, CHARLES F. J ACOBSEN,

.of New York, in the eounty of New York and Ny invention has relation toreflectir g cha-ir deliers for use in public or private buildings;

and it consists, first, in the hereinafterdescribed construction andnovel arran gement of the reflector, which s composed of three or moresections, having the form of truncated polygonal pyramids or cones ofdifferent sizes, and placed concentrically one within the other,according to their dimensions. The object of this part of my in ventiouis to produce a large extent of reflecting surface within a limitedcompass, and to so constitute said refiecting surface that the rays oflight shall be reflect-ed outwardly, as Well as inwardly and downwardly,to as great a distance and with as much power as may be required. Thesecond part of my invention con sists in so eonstructin g and arrangingtheforin orframc which encompasses the refiector that its ornamentedexterior surface shall be full y illumin ated by mea-ns of the lightsbelow it and be displayed to the best advantage. The third part of myinvention consists in the arrangement of burners in their relation tothe sections of'the reflector and to the exterior surface of theencompassing frame, as hereinafter described.

In the accompan'ying drawing, illustrating this invention, A representst-he main tube of the chandelier, through which gas is supplied to thedepending burners, and which sustains the various parts of thechandelier. B represents a circular tube surrounding the tube A near itslower end, and attached to it by means of radiatiug pipes b. The tube Bis supplied with burners, and, being flanged, has suspended from itanumber of glass pendants, b. E represents a second circular tube,constructed and arranged in the same manner as the tube B, but is ofgreater diameter than the latter, and is placed some distance above it.The radiating pipes 13 supporting the ring 13 are provided with burnersso that light may be thrown directly on the innermost reflector. A thirdcircular tube, which should be of less diameter than the tubes B B andbe placed above them, may be used to light the reflectol correspondingto it. The burner-tubes B B being of different diameters, the flames andupward Currents of air will not nterfere With each other. These tubesare adapted in size and arrangement to the positions of the sections ofthe reflector, hereinafter describethso that the light may be thrownfully, clearly, and directly upon the reflectin g surt'aces. O 0 0designate the different refiectors or sections of the compoundrefiector. These sections are of the form of truncated polygonalpyramids or cones, their refieeting surfaces made of glass coated withthe proper material. The'glass may be either plane, fluted, orotheravise. The inner and outer refiectors O O, being arranged asupright pyramids, face inwardly and downwardly. The intermediatereflector is arranged as an inverted pyramid, and hence faces outwardlyand downwardly. It will be seen that, by this arrangement of thereflecting surfaces, the reflected light is more Widely diffused. Theframe or base, to which the reflectors C 0 are attached, may be cast inone piece. Between the upper edges of the reflectors G 0 and of therefiector (3 and the tube A, spaces D are left for the passage of thecurrents of air rarefied by the heat of the flame. The reflectors O Care supported by the pipes c c of a spider, which radiates from the tubeA. The reflector O is attached to the form or frame surrounding it,which is suspended by chains c The precise arrangement for support ofthe refiectors and encompassing form is not material in this invention.The lower part of the reflector O is provided with a flange similar toflanges on the tubes B B On these flan ges a prismatic net-work,gracefully han gin g, is suspended, or, instead of said net-work, glasspendants may be used. The object of the prismatic net-work or pendantsis to increase the brilliancy of the efect and to soften and diffuse thelight. When the chandelier is used in parlors or apartments Where asomber light is desirable, clouded glass may be used for the prismatienet-Work or pendants. E represents a, fra-me or form encom mssing therefiectors. This form mey be made of Wood, glass, metal, or any othermateria-l or combination of materials-opaque or transparent. The shapeof this form may be either circular or-polygonal, with its surfeceeonczwe and facin g downwardly and outwardly. An inverted frustum of acone approXimates the nature of the form. The concave surf-ace of saidform is highly ornamented by means of molding, pictures, 85o., uponwhich the light from the burners falls and therefore displays to fullView.

The form or rin g surrounding the reflectors has heretofore beenconstructed and arranged as an uprighttruneated cone or pyramidconsequently, its ornamentation could be only imperfectlyobserved, ifseeu at all. Another objeetion to the old-style form is the liability ofdust to accumulate and eloud the picturesque designs upon its face.

The present invention is free from both these objeetions, and is besidesmore graceful in its arrangement. The surfaee of the form may toadvantage be provided With glass paneis, to 'be used as refiectors ofthe light oi' surronnding' burners.

The spider-tubos c c are bent down outside the refieetor C, and theneeextend outwardly through suitable opening's in the form, and areprovided With bnrners, and, it' neeessary, With globes. These burnersserve to give'additional brillianey to the snrface of the form, as Wellas to light up the eeiling so as to display the freseoes. Branch tubes 0may be extended 'out above the form When desired for the purpose oi'illuminating' the eiling. On the outer sur'aee of the refieetor O Iplace silvered glass, eiiher plain or fluted, and 'thus provide arefleetor which will reflect the rays from the burners 0 of thespider-tubos c to the ceilin I sometimes make the inner surface of theform E a refieetor for thesame purpose.

I have mentioned that the form E may be either opaque, transparent, orsemi-transparent.. The object in making the form transparent orseini-transparent is to letthe light from the spider-tubes e* berefleoted by the outer refiecting surfa-ce of the section O through itso that the pictures or designs upon the form may be Well illuminated.When the form is made of Wood or other opaque material, I purposeproviding it with transparent or semi-transparent paneis G, ornamentedaeeording to taste.

W'ha-t I elaim as my invention, and desire to secure by Letters Patent,is

1. The form or frame llmade of transparent or semi-tran sparentmaterial, or of opaque material with transparent or semi-transparentpaneis, in combination With the burners 0 so *disposed as to transmitra-ys of light through the transparent or semi-transparent paneis, asand for the purpose specified.

2. The refieetor G, in combination With the transparent,semi-transparent, or gl ass-pan eled form E, and the burners 0snbstantially as specified.

3. In a reflecting ohandelier, the refleetors O C (3 constructed andrelatively arranged in the manner and for the purpose specified.

4. In a refleetin g chandelier, the ornainented form or frame Eeneompassing one or more refieetors, and upwardly and outwardly fiaringso that the lights from below may be casron its exterior snrl'aee, asand i'or the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presenee of two wituesses.
